Abstract

La présente invention concerne un procédé de fabrication de pièces coulées en acier (110) destinées à fournir un élément d'usure. Selon l'invention, le procédé de fabrication fait appel à au moins une étape consistant à préparer au moins un insert de renfort (115), et à une étape (11) consistant à préparer un moule (111) pour la pièce coulée (110) à fabriquer, l'étape (11) de préparation du moule (111) faisant appel à une étape secondaire (14) de disposition dudit insert de renfort (115) à l'intérieur du moule (111) dans les zones qui correspondent aux zones de la pièce coulée (110) coïncidant avec celles qui, en utilisation, seront les zones de l'élément d'usure les plus soumises à une usure, et à une étape ultérieure (12) consistant à couler de l'acier à l'intérieur du moule (111). L'étape de préparation dudit insert de renfort (115) fait appel aux opérations de remplissage d'un contenant tubulaire sensiblement filiforme (116) avec un mélange de poudres ou de petites pièces (118) et de mise en forme, également du point de vue spatial, du contenant tubulaire filiforme rempli (116) pour obtenir la structure physique dudit insert de renfort (115).
